在这项研究中，两种类型的铸态组织的薄带连铸生产冷轧和退火，研究初始组织的无取向硅钢的织构演变和磁性能的影响。结果表明，与具有强Goss（{110}）织构的细晶板相比，具有显著{100}织构的粗晶板呈现出较强的λ纤维（< 100 >）/IND）和较弱的γ纤维（< 111 >）//ND）织构< 001 >。退火后，前者以η纤维（< 001 >//RD）织构为主，在{110}取向处有一个峰< 001 >，而后者由较强的{111}< 112 >和相对较弱的{110}< 001 >织构组成。此外，一些尺寸为30-150 nm的析出物限制了退火过程中晶粒的生长，导致粗晶试样中晶粒尺寸为46 μ m，细晶试样中晶粒尺寸为41 μ m的再结晶。最终，具有强{100}织构的粗晶带的最终退火板获得了较高的磁感（类似于1.72T）和较低的铁损（类似于4.04W/kg）。(C)2018由Elsevier Ltd代表Journal of Materials Science & Technology编辑部出版。
In this study, two types of as-cast microstructure produced by strip casting were cold rolled and annealed to investigate the effect of initial microstructure on the textural evolution and magnetic properties of non-oriented silicon steel. The results indicated that the cold-rolled sheets of coarse-grained strip with pronounced {100} components exhibited stronger lambda fiber (< 100 >)/IND) and weaker gamma fiber (< 111 >)//ND) texture as composed to the fine-grained strip with strong Goss ({110}< 001 >) texture. After annealing, the former was dominated by eta fiber (< 001 >//RD) texture with a peak at {110}< 001 > orientation, while the latter consisted of strong {111}< 112 > and relatively weak {110}< 001 > texture. In addition, a number of precipitates of size similar to 30-150 nm restricted the grain growth during annealing, resulting in recrystallization of grain size of similar to 46 mu m in the coarse-grained specimen and similar to 41 mu m in the fine-grained specimen. Ultimately, higher magnetic induction (similar to 1.72T) and lower core loss (similar to 4.04 W/kg) were obtained in the final annealed sheets of coarse-grained strip with strong {100} texture.
